Phase-selective hydrothermal synthesis of hydrous lithium titanates nanoparticles as a precursor to Li4Ti5O12 anode material for lithium ion rechargeable batteries

Spinel Li4Ti5O12 hollow nanospheres prepared with colloid carbon spheres as templates for high power Li-ion battery anodes

“…The relatively high charge/discharge plateau can effectively suppress the reduction of organic electrolytes and the deposition of metallic lithium, making the batteries of high safety. [9][10][11] However, the rate performance of Li 4 Ti 5 O 12 anodes was significantly restricted by the sluggish kinetics of electron and lithium-ion transport. 12,13 Thus, enormous attempts [14][15][16] have been carried out to improve the rate performance by enhancing the conductivity, including surface coating or admixing with carbon and other electronically conductive materials, reducing particle size and tunning the morphologies, and doping with isovalent or supervalent cations.…”

Molten Salt Synthesis of Different Ionic Radii Metallic Compounds Doped Lithium Titanate Used in Li-Ion Battery Anodes

“…One strategy is to improve electron transfer by ion doping, surface modi cation, and/or incorporation of carbon [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] . The other approach is to reduce the electron and Li-ion diffusion lengths by producing nanostructured analogues of Li 4 Ti 5 O 12 itself [27][28][29][30][31] . Among these methods, ions doping can ef ciently improve the intrinsic conductivity of LTO, smaller particle size can shorten the Li-ion transfer route, thereby improving the rate performance.…”
